IDOFFING-WIRE.

' To all whom it may concern.

Be it known that we, PETER J. HINns and EDGAR S. Foams, both citizens ofthe United States of America, residing at Holyoke, in the county ofHampden and State of Massachusetts, have invented new and usefulImprovements in Dofiing-VVires, of which the following is aspecification.

This invention is designed to facilitate the operation of doifing thefilled bobbins on a spinning frame and replacing them with emptybobbins, and is an improvement upon the dofiing wire of our prior PatentNo. 1,000,909, issued August 15, 1911.

Before removing" the filled bobbins or cops, it is necessary to swingthe thread leading to each spindle out of the way of the operator, andprior to the .invention shown in our said patent such movement of thethreads was done by hand. By the means shown in our patent, however, anoperator at each end of the spinning frame raised-a wheeled carriage,mounted on a track secured to the front of the upright supports at eachend of the frame, practically as high as the top of the bobbins, thenswung arms pivoted to the said carriages,

over the bobbins, and the dofiing wire car-.

'ried by said arms engaged all the threads at once and swung them awayfrom their respective spindles as the arms were moved back of thespindles and the carriages dropped to their lowered position.

By our present improvement, a much simpler and more economicalconstruction of doiiin device is provided, and while the prior do ngwire required that the operator employ both hands in the two movementsof first raising the carriage and then swinging the arm carrying thewire over the spindles in order to operate the device. our

present invention enables this operation to be accomplished by a singlemovement and by one hand of the operator.

To this end,'an important feature of the invention comprises meanswhereby an arm or carrier for thedofling wire is pivotally secured to asingle fixed point on the upright support at the end of a spinning frameand is arranged to be vertically movable relatively to such support;said arm being both vertically and pivotally movable.

A very important advantage of the present improvement is that by reasonof Specification of Letters Patent.

the simple and li ht construction of the carriers for the do%ng device,practically all danger of breaking the threads leading to each spindleis eliminated, whereas in the device of our prior patent the extraweight of the traveling wheeled carriages was apt to break the threads'when thecarriages were dropped by a careless operative and the dottingwire was in engagement with the threads.

Further objects of the invention are to provide a doliing device whichmay be easily and quickly attached to spinning frames, which cannoteasily get out of order, and which will have capacity for greatlyincreased specd of operation.

Referring to the drawings, wherein a pro ferred embodiment of theinvention is illustrated, Figure l is a front view of a portion of aspinning frame with the dofiing device mounted on each end support; andFig. 2 is a view, partly in cross section, on "the line 2-2 of Fig. 1,looking toward the right;

The usual spinning-frame construction comprises upright supports a, a ateither end, a bolster m on which the spindles b are mounted, and avertically movable ringrail 6, all being arranged in the usual and wellknown manner.

A block f is pivotally secured to the upstanding portion ofthe member n by means of a bolt is, said block 7 being suitably bored toreceive a sliding carriage or arm g. This arm g has at its upper portiona'turnbuckle h threaded therethrough, and at its lower portion a head orflange to limit its upward movement. The turnbuckle h has an eye inwhich the end ortion of the doffing wire 6 is secured. uplicate slidingarms or carriages gare similarly arrang dto each support, and the wire 0is adjustably secured thereto, as will be readily understood Our dottingdevice is filled, the spinning is'sto'pped, with the ringrall in itslowered position. Operators at each end of the spinning frame manuallygrasp and lift the respective arms 9, slldingthem upwardly in the blocksf until the wire a may be swung over the tops of the spindles b andagainst the threads '0 leading to I and empty ones replaced, when thesliding ing while v eration;

mods g are operated ina reverse manner to swing the dofiing wire 6 fromthe position shown in Fig. 2 back to that as shown in Fig. 1, when thespinning may be resumed.

It will be readily seen that we have provided a doffing device of theutmost simlicity of construction and one which may e operated with greatease and facility,

the operator lifting and swinging a rod 9 to position the dofling wire 6in either operative or inoperative position by a single movement andwith only one hand. Also the light weightof the entire movable portionof the dofiing device renders dama e to or breakage of the threadsunlikely. guch lightweight also minimizes the labor of do-fipermittingincreased speed in op- In the device of our prior patent it wasnecessary to use a track on which the wheeled carriage could be raisedand low ered, and if said track was bent, either by accident or by thetension of the dofling wire, the operation of the carriage wasdifiicult, whereas in our present improvement, by affixing the block 1by means of a'strong pivotal connection at a fixed point on the anylikelihood of derangement of the moving members or difiiculty in theiroperation is eliminated.

Another advantage of considerable practical importance inthe device ofour present invention is that it may be applied to a" spinning framewithgreat ease and rapidity, necessitating merely the affixing of themembers 7], to the front of the frame, where as the device of our priorpatent required the afiixing, adjustment and truing of parallel trackson which the wheeled carriages traveled.

Having described our invention, what we spinning frame,

-spinning frame claim as new and desire secure by Letters Patent is:

1. In combination with the spindles of a spinning frame, a dottingdevice comprising a wire supported by two carriers, each carrier beingpivotally mounted on an end suping provision for vertical slidingmovement relatively with said support, whereby the wire can be movedfrom a position in front of the'spindles over the tops of the spindlesto engage the threads leading thereto by a simultaneous vertical andpivotal movement. 2. In combination with the spindles of a a doflingdevice comprising two arms pivotally mounted at fixed points on theframe, said arms being constructed and arranged for sliding movementrelatively with said. pivotal connection, a wire carried by said arms,and adjustable means to connect an end of the wire to each arm.

3 In combination with the spindles of a spinning. frame, a doflingdevice, comprising a wire carried by means mounted on the at a fixedpoint, which means have provision for simultaneous vertical and pivotalmovement relatively with said frame to cause said wire to engage thethread leading to each spindle and to hold said threads away from saidspindles.

4. In combination with the spindles of a spinning frame, two separatedfixed supports, a holding device pivoted to each support, a rod held byand movable relatively to each holding device, a wire subtended betweensaid rods whereby said rods may be moved to position said wire in frontof, or behind the spindles, and in either position to move the wirelengthwise of the spindles.

5. In combination with the spindles of a spinning frame, two separatedsupports, a holding device pivoted to each support, a rod held by andmovable longitudinally with respect to each holding device, a wiresubtended between said rods whereby said rods may be moved to positionsaid wire in front of, or behind the spindles, and in either posit-'onto move the wire lengthwise of the spindles.
